i Application filedyMay 2, 1R84. (No model To all whom it may concern:

Be it known that I, WiLLrAM H. DoUGHrY, a citizen of the United States,and a resident. of New York, in the county of New York and State ofNewYork, haveinvented certain new and useful Improvements inRefrigeration,` of which the following is aspeciiication.

rlhis invention relates to improvements in refrigeration forrailroad-cars, die., and is 1o adapted either forfstationary or movablestructures, one of the purposes for which itis designed beingrailroad-cars for the'transportation'of perishable articles of food.

. In Patent No.u 294,209, granted to me onthe .15 26th dayof'February,1884, -Ishow chambersl supplied with ice and arranged to receive cnr-'rents of lair, which are cooled by coming in contact with the ice withinsaid chambers.

In the present instance airis forcibly supplied nished not with ice butwith a series of perforated pans, which receive a stream for streams ofcold water from a sourceoutside the refrigerating structure. The airisby this presents itself to the airain a finely-divided condition and iscarried along with it to the bottom of the cooling-chamber, at whichpoint it is liberated and passes into the provisionv.

compartment, the wateriowing through "a waste-pipe and then conductedback into the water-supply tank for use again'. rlhe result of thisoperation is that the air is greatly reduced in tempera-ture andrendered suitable for purposes of effective refrigeration. vThe wateremployed is reduced to avery low temperature,. by means of ice and saltor -other suitable refrigerating agents, in a chamber or compartmentisolated from th'e provision- 40 chamber, and is conducted by a pipe tothe pans with perforated bottoms, as already explained.v

The claims at the end of this description define the points of novelty'inl :my present i.n.- vention.

In the accompanying drawii'1gs,Fig\\re 1 shows alongitudinal verticalsectional view of astationary structure embodying my invention, providedwith 'a'serics of cooling and 5o provision chambers or coinpartmentsmndFig;

to similar cooling-chambers, which are furp arrangement forced into thecold water, which' `pipe which supplies the pans.

`sprays or iets oi 2 is a longitudinal sectional view showing theapplication of my improvements to a movable structure-a railroad-ear inthis instance. l

In Fig. l, A represents a compartment in the front end of which is acooling-chamber, 55. B, and in the upper front corner of -which is a fanor blower, "G, of any desirable pattern. The ian-chamber communicateswith the u pper end'of the cooling-chamber B, `and the lower portion ofsaid chamber lll is in communication with the interior oi' theprovisionchamber Af.'

F represents a line at the top of chamber y A, and it is furnished withvalvesff, con-v l nected to each other by a rod, e, so that. the ,65air-currents from `the fan may be directed into either ofthecooling-chambers at will` as may be readily understood.

. H is another ilue, loeatcdeabovethe firstf mentioned flue, andprovided with a yalve, h. 7o

The air is extracted from the provisionrcham- .bers by the fan G throughsaid'fine H in a manner rendered plain l'by the drawings. lit is by thismeans that the air within the refrigi erating structure lis keptconstantly passing through the cooling-chamber, and thereby re Y tainedat a proper ten'iperatnre fior refrigerat-y ing purposes.V

vNear the top of thecooling-chamber B is a: pam-L, attached to threesides of the walls of 8o said chamber, with 'a space between the edge ofthe pan'and the fourthsideoi the chanr ben Beneath this pan is a seriesof similar pans, L'3 L L, 85o., arranged as shown, andhaving theirbottoms finely perforated.' 85 M is a cooling-chamber for 'the 'waterwith which the pans are supplied. In this instance I show a pump forconveying the water tothe When deposf ited in thepan's, the water fallsfrom onetothe other thereof in sprays or jctsthrough the pennratedbottoms,-and from the last panoi the series to the bottom of thecooling-chamber, from whence it passes into the drainppe to be. pumpedor otherwise conducted bac-k to the chamber M. y The current of airproduced bythe fan or. blower G is forced through the spaces between thepans, and consequently through the cold 'water to the bottom of the 1c(into the provision cha let for the air.

` .there m-ay be two or more pipes communicatair may ing with avcorresponding number of pans;

and, if desired, the upper pan may extend to all sides ofthe chamber B,and the current of be introduced into the cooling-chamber.' below saidupper pan. v

j It is obvious that the arrangement above described may be reversed,the fan or blower located in the lower portion of the apparatus, and thecurrent of air-forced upward through l the cold sprays or, jets andpassed into the pro- I' .rangement is intended .to be shown in Fig. 2l,25

poses.

fallingsprays or jets of c'old may be provided with flues and valves ordamperssimilar to those embodied-in the conc vision-chamber near thetop. Such an arof the drawings. In this view J represents airailwaycar-tted up for refrigerating purber and with a provisioncompartment, and -the cold water conducted from the tank, for instance,is delivered onto the pans at the top ofthe cooling-chamber, while theair-current is forced., by the fan or blower G, for instance, throughthe bottom of said chamber into the water. f This modified constructionof my inventionl struction shown in Fig. :1.

This is an effectual means" It is constructed with a cooling-cham- Incase the air-current is forced in at the bottom of the cooling chamber,the pipe through which the air passes-may be provided near its upper endwith a surrounding bowl or trough, It, into which any waterwhich may becarried up by the current of air will fall of its own gravity, and maybe conducted awa by a suitable waste, serves as a trap inthe same senseas does the bent pipe P inthe embodimentof v myinvention shown in Fig.1.
